[英]How to convert object timestamp to firebase timestamp?
I want to convert the following timestamp:我想转换以下时间戳:
Object {
"_nanoseconds": 725000000,
"_seconds": 1621386976,
}
to this timestamp:到这个时间戳:
t {
"nanoseconds": 725000000,
"seconds": 1621386976,
}
How can I go about doing this?我怎么能 go 关于这样做? I am stumped.
我难住了。 I have tried
toDate()
and variations of this, but nothing is working.我已经尝试过
toDate()
和它的变体,但没有任何效果。
Found this on reddit:在reddit上找到这个:
getTimeText = (timeObject: any) => {
// Convert to time text once it's of type firestore.Timestamp
const getTextFromTimestamp = (timestamp: app.firestore.Timestamp) => {
return this.timeAgo.format(timestamp.toDate())
}
if (timeObject instanceof app.firestore.Timestamp) {
// Check if Timestamp (accessed from client SDK)
return getTextFromTimestamp(timeObject)
} else if (Object.prototype.toString.call(timeObject) === '[object Object]') {
// Check if it's a Map (accessed from Cloud Functions)
const seconds = timeObject['_seconds']
const nanoseconds = timeObject['_nanoseconds']
if (seconds && nanoseconds) {
const timestamp = new app.firestore.Timestamp(seconds, nanoseconds)
return getTextFromTimestamp(timestamp)
}
}
console.log('Couldn\'t parse time', timeObject)
// Fallback
return 'some time ago'
}
